We currently have a 09 burb with the 5.3 and 3.42 gearing. We just got a camper which is about 7500 pounds fully loaded, so we are looking to upgrade towing vehicles. I would likely trade the 09 so this would be my daily driver. Would the 6.2 denali xl pull the load fine, or should I look at a 3/4 ton with the 6.0? It looks like the 3/4 tons came with either 3.73 or 4.10. What gears are available for the denali xl?
